Bill,
I looked at the Voyager for a good antenna on 160 and 80, but gave it up 
for an inverted L with a good ground system, which I haven't built 
yet. I'm convinced that good performance, in my situation without a real 
tall tree or mast, is to get up as high as possible with a vertical and top 
load it or use an inverted L configuration, and then put in lots of ground 
radials. I haven't modelled it, but I think I can get good dual band 
performance on 160 and 80 with an inverted L, and I have enough real estate 
for an inverted L. I can get four band performance with low angle 
radiation on 160 through 30 meters with a top loaded 45' vertical and lots 
of ground radials, so EZNEC says.
